MECHANISM FOR 'YAISSOCIATING SHE-NETS.

SPECIFICATION forming part of Letters Patent No. 545,459, dated September 3, 1895.

Application filed Octoberl, 1892 To aZZ whom it may concern:

Be it known that I, LUTHER C. CRowELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Mechanism for Associating Sheets, fully described and represented in the following specification and the accompanying This invention relates. to means forassociating small or supplemental sheet lengths with large or main sheet lengths in the production of a compound product which may not be composed by simply bringing together a number of the aforesaid main sheet lengths; and although these improvements may be otherwise usefully employed, they are especially advantageous in printing-machines for the production of newspapers, wherejthe product at times is required to be made up of such a number of pages as renders it neces-- sary to combine a small sheet, as one having, say, two or four printed pages, with a large sheet, as one having, say, four, eight, or twelve, pages, as forming, say, a six, ten, twelve, or fourteen page product.

The invention principally consists in combining with a receiving-cylinder running at the high speed necessary to the manipulation, of the main sheet lengths a carryingcylinder running at a relatively slower speed, adapting it to the manipulation of small or supplemental sheets, with which latter cylinder are combined means for severing a supplemental web into such sheets, and for delivering them from the carrying-cylinder to the receivingcylinder, by which organization small or supplemental sheets are carried forward at one speed of onward movement and delivered to the receiving-cylinder into association with the main sheet le'ngth carried thereby, thereafter traveling concertediy with the main sheet length and being simultaneously treated therewith, as'by printing. I

The invention also includes various combinations of parts, fullyhereinafter pointed out and claimed.

A practical embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, Fig. 2 a plan Serial No. 447,503. (N 0 model.)

view, and Fig. 3 a sectional elevation, of aprinting-machinecontaining the present improvements, while 'Fig. 4 is an elevation'of the principal cylinders of the associating mechanism detached from the printing-machine, of which Fig. 5 is an enlarged end ele- 'vation; v The principal elements of this improved sheet-associating mechanism are a cylinderoo 21 for carrying small or supplemental sheets,

a cylinder 20 for receiving the said sheets, as well as the large or main sheet lengths, and acutting mechanism for dividing a web into the small sheets carried by the cylinder 21. The carrying-cylinder 21 is suitably mounted in bearings and provided with means for retating it at a speed that is appropriate to the size of the sheet it is to carry and deliver to the cylinder 20. In the instance shown this sheet is a page length and equal to half the circumferential extent of the cylinder20, and hence the surface speed of this cylinder will be one-half that of the cylinder 20. Although the cylinder 21 might be of a size to carry one such sheet only, it is preferred to make it 'ofdouble size, as shown. It is provided with o'ne'or two sets, as may be required, according to its size and consequent number of sheets it is to carry, of sheet holding, carrying,

and releasing devices, which, as illustrated,

are impaling-pins, as 6 7. Behind the line occupied by each set of these pinsis arranged a vibrating throw-0E plate, as 11 12, which might be series of arms, if desired. These arms or plates are pivoted to the cylinder and arranged to lie, when closed, in recesses therein, so as to be coincident with the peripheral face of the cylinder, and they are vibrated outward at suitable times, so that they will 0 lift the head of each sheet off from the pins and press its leading edge outward by means of rock-arms, as 14 15, the studs or bowls of which run in the groove Not a cam fixed to the side frame, which groove is so shaped as to move said platesquickly outward as they approach their meeting-point with. the grippers 3, and in like manner. withdraw them into their recessed seats coincident'with the periphery of said cylinder when their officers: has been performed.

The sheet-holding pins, as 6 7, might be stationary and simply project a suitable distance beyond the facial surface of the cylinder 21, so as to properly pierce the leading end of each sheet, suitable holes being provided for their passage through the plates 1112. As herein shown, these pipes project through recesses in the shell of the cylinder 21 and normally protrude through small holes in the plates 11 12. They are carried by rock-shafts, which, by means of a rock-arm and a link, as S0 or 81, are so connected with a rock-arm on the shaft of the throw-off plates 11 or 12 as to move concertedly therewith, the relative cooperation of each plate and set of pins being such that the pins rock slightly rearward as the plate moves outward, and thus accomplish a smooth withdrawal of the sheet from.

the pins. The pins might, however, be made to reciprocate, and thus be alternately pro-I truded to engage the sheet and withdrawn to release it.

coacts to sever or partially sever a web of paper into sheets. This blade Sis carried by a cylinder 23, that is arranged in co-operativej relation to the cylinder 21 and geared to run These cutting ings, and, as shown, is provided with means for rotating it at such surface speed as is appropriate to the manipulation of a main web, which is ultimately to be severed into sheet lengths, forming the principal part of the desired p'roduct, its circumferential extent being of the,

length of two pages. In this instance the cylinder 20 is geared to run at twice the surface speed of the cylinder 21; but this may be vaa ried under suitable circumstances. This cylinder is provided with sheet receiving, retaining, and releasing devices-such, for instance, as grippers 3that are vibrated in any common manner, and which co-operate with bearers 2 to receive a sheet pressed outward by the throw-off plate 11 or 12 from the cylinder 21, clamp the same on and carry it around upon the cylinder 20, which grippers in their return movement to reach a position for en gaging the sheet pass through recesses "71, It will now be understood that a web of paper, as N, led from a supply-roll, as S, passed with which the plates 11 12 are provided.

around a feeding-roller, as 2 1, and entered between its surface and that of the cylinder 21, will be impaled by the pins 6 or 7, and

thus be held to and carried around upon the surface of that cylinder, and that as the point of c oaction of the cutting-blade 8 and cuttinggroove 1 or 9 is passed the web will be severed transversely into sheet lengths, the heads of which will be retained by the pins, while a Slightly in advance of the said pins this cylinder is also provided with cut-j ting-grooves 1 9, with which a cutting-blade 8 so guide its leading edge that the latter will be presented in proper position to be seized by the grippers 3 of the cylinder 20, (which pass freely through recesses 71 of the plates 11 13,) be pressed thereby onto the bearers 2, and thus seized become attached to that cylinder,

whereupon said sheet will take up the speed of said cylinder and be laid upon the surface thereof and be moved onward thereby.

In the organized machine shown the several cylinders and other rotating parts are suitably journaled in the side frames, and the cylinders 10 2O 30 are geared together to turn in unison at a speed of surface movement required to be imparted to the main web or sheet lengths thereof by means of wheels 51 52 53 54, being driven in this instance bya pinion 55 on the driving-shaft. The carryingcylinder 21 is revolved at onehalt" the surface speed of the receiving-cylinder 20 by means of a wheel 56 on the shaft of cylinder 20, which meshes with a wheel 57 of twice its size on the shaft of cylinder 21, and the cutting-cylinder 23 is driven at the same surface speed as cylinder 21 by means of a wheel 58 on the shaft of the latter, which meshes with a wheel 59 on the shaft of the former.

A conveying-cylinder 25, cooperating with the cylinder 30, is driven in unison with that cylinder by means of a wheel 60, meshing with the wheel 53, and the wheel 60 in turn drives a tape-pulley 26 at a like speed by means of a pinion 61. Delivery-cylinders 41 42 arelikewise driven at the surface speed of the principal mechanisms from the wheel 51 through an intermediate 62 and wheels 63 64:. All of the gearing thus far described is without the framework, and hence not shown in Fig. 2, which is a view from the gear side of the machine, taken just within the side frames.

The cylinder 30 is provided with bearers, as 4, and coacting grippers, as 5, operating, as do the like devices ofcylinder 20, to seize, carry, and release a sheet, the proper vibrations of the grippers being produced by rockarms or in any well-known manner.

In Figs. 4 and 5 the grippers 3 of the cylinder 20 are shown as provided with a rock-arm 13, a stud or bowl on the end of which runs in the groove of a stationary cam 33, which thus rocks said grippers to close and seize or to open and release a sheet or sheets in a common manner, and the grippers 5 of cylinder 30 are operated by a cam, as 34, and the grippers 16 of the cylinder 25 by a cam, as 75,

(see Fig. 2,) in the same manner and to perform like functions. From an examination of Fig.2 it will be understood that the forms ICC upon the type or form cylinders 1040 may be four pages lengthwise and two pages.

- or at one side of the machine, to the other side of the machine for delivery by the cylinders 41 42, which are at the same side of machine as the carrying-cylinder 21. By such an arrangement the type-cylinders may carry at one end such forms as are required to print a main web or sheet lengths thereof, and at the other end with such forms as are desired for the printing of the small or supplemental sheets received from the carryingcylinder 21. With the cylinders 10 and 40 provided with such forms or printing-plates it will be understood that a web W, led from a roll M, guided, directed, or carried by suitable means to the cylinder 20, as by pulleys, so as to enter between the cylinders 10 40, as shown in Fig. 3, will, in passing between the type-cylinder 10 and the impression-cylinder 20, be printed upon one surface by the forms upon the cylinder 10, and then, led between the cylinders 20 30 and 30 40, will, in passing between the latter, be printed upon the other side by the forms carried by the cylinder 40, which web, being of a width equal to half the length of said printing-cylinders, will be led over guide-rollers 37 38, and from the latter pass up over the turning-bar 39 and over and under the turning-bar 49, whereby it will be shifted laterally or over the other half of the length of the printing-cylinders as it passes outward toward the delivery-cylinders 41 42, which it reaches by being carried over guiderolls 43, 44, and 45. These delivery-cylinders 41 42 are provided with means for cutting such web into sheets, and the cylinder 41 with means for collecting many sheets upon its surface, and with means whereby when the predetermined number of sheets have been collected the same may be directed from its surface out to a piling or folding mechanism for simiiltaneousdelivery. The cutting mechanisms of these cylinders 41 42 are of ordinary construction and need no description, as any sheet-severing mechanism may be employed. The means shown for holding successive sheets upon the cylinder 41 consist of pins 18, which impale their leading ends, formed when the cuttingdevices operate. The means shown for delivering the collected sheets from this cylinder consist of throw-off arms 19, which, underlying the heads of the sheets where they are impaled by the pins 18, are vibrated at suitable intervalsin this case at each third revolution-by means of a rock-arm 76, attached to their shaft, which runs in the groove of a cam 46,

run in unison.

(see Fig. 2,) which cam is revolved at the proper time to accomplish this result by means of a wheel 66 on the shaft of cylinder 42, which meshesv with a properly-propor tioned wheel 66 on the shaft of cylinder 41. (See Fig. 1.) As here shown, the pins 18 are simultaneously vibrated in opposite directions by means of a rock-arm and link connecting with the rock-arm 76, as seen in Fig. 3, whereby said pins are moving inward when the said throw-off arms are moving outward; but none'of the mechanisms connected with these cylinders 41 42 are herein claimed, the same being shown for illustrative purposes only. When the throw-off arms 19 press the collected sheets outward from the cylinder, they direct them between rollers 47 48, over which run carrying-tapes by which said collected sheets are delivered in apack over folding-rollers 9O 91 and beneath a vibrating folding-blade 70, whereby the pack is folded.

The circumferential dimensions of the receiving-cylinder 20 being, as here illustrated, two pages in length, and the supplemental sheets produced by the cylinders 21 23 being one page in length,said cylinder 20 is capacitated to carry an extent of material-which is twice the length of the supplemental sheet, and this is received from another source in the form of aweb which is to be severed into lengths composing the main sheets of an 111- timate product. The small or supplemental sheet delivered by the cylinder 21 to the cylinder 20 will therefore, although on another part of the surface of the cylinder 20, be associated with a sheets length of the main web, which is larger than the supplemental sheet, so that the two will thereafter in definite relation be concertedly manipulated.

In the illustration of a practical use of this associating mechanism, it is shown as com-, bined with a perfecting printing-machine, of

which the receiving-cylinder 2O acts as one of the impression-cylinders and co-operates with 2. type or form cylinder 10 'in producing an impression upon one surface of a sheet or web, While a similar impression-cylinder 30 and type or form cylinder 40 in like manner operate to produce an impression upon the opposite surface of such sheet or web, the four cylinders 20 10 30 40 being geared together to At one end these type-cylinders'lO 40 will be provided with the plates or forms necessary to the printing of the main sheet or web, and at the opposite ends with the plates or forms suitable for the printing of the small or supplemental sheets. Each small or supplemental sheet carried by the cylinder 21 is quickly drawn from its surface by the grippers 3 of the cylinder 20, which seize its leading end and lay said sheet upon the surface of the cylinder 20, which sheet will thus be carried by said cylinder 20 between it and the cylinder 10, where it will be printed upon one surface, and then between the cylinders 20 30, where these grippers 3 open to release the sheet and deliver it to the grippers 5 of the cylinder 30, which latter will close to seize it, lay it upon the surface of the cylinder 30,

and carry it between that cylinder and the cylinder 40, where it is printed upon its other side, said grippers 5 finally opening to release the sheet for delivering from said printingcylinder 30 to the grippers 16 of the conveying-cylinder 25, which grippers in turn open to allow said sheet to enter a tapedpathway connecting this conveying-cylinder with the delivery-cylinders 41 42, This pathway consists of a set of upper tapes 35, that run from said cylinder, pass over the tape-pulleys 26,

thence pass around pulleys 27, and return to said cylinder over pulleys 28,and of an under set of tapes 36, that run from pulleys 29 in I contact with the cylinder 25, pass over the pulleys 26, run under the pulleys 27, and return to the pulleys 29 over pulleys 37 32,

mechanisms to sever the web into suitable sheets, a suitable delivery mechanism, and

the use of a main web (V of the full width of the machine, or equal to the length of the printing-cylinders, such a machinemay, without the supplement-introducing mechanism,

, produce at each revolution of its type and impression cylinders eight products of two pages each, or four products of four pages; each, or two products of eight pages each at each revolution; and by using a three-quarter web as the main web W, and providing each type'cylinder with six forms or plates, constituting two sets of duplicates arranged in threes longitudinally and in twos circumfer entially, it will result, by transferring two thirds of the web over the remaining third, that at each revolution of the printing-cylin- As this cylinder 41 is of a length equal to that of theshort sheet, and it makes two} revolutions to each delivery of a sheet uponj its surface, it follows that it will collect ashort sheet and associate it with the web, which will be severed into a length equal to said shortj sheet and receive thereon. another lengthl likewise severed, so that the ultimate result is three sheets of equal length, (although the supplemental sheet of which may be of lessf width), which are delivered from said cylinder in a single body or pack to the folding:

printingmachine of the construction illustrated, when provided with this supplemental sheet-introducing mechanism, is ca-; pacitated to produce avariety of products. Its type-cylinders are of a size which adapts them to carry eight forms or plates arranged in fours lengthwise and intwos circumferem:

ders two six-page products will be produced. If the forms are appropriate, these two sixpage products would, if associated and delivered as a single product, constitute a twelvepage product, while the two eight-page products before referred to would, if associated and delivered in like manner, constitute a sixteen-page product; but in orderthat a ten ora fourteen page product may result it is necessary to add to the product made from the main web W a small or supplemental sheet consisting of two pages appropriately introduced into the machine and associated with the main sheet or sheets, which small or supplemental sheet will be half the width of the main sheets.

In order to make a product constituting, say, a ten-page newspaper, the type-cylinder will be equipped with appropriate forms, as follows: they will carry at one end the forms for themain sheet of eight pages on one-half their longitudinal extent, the forms being disp'osed so that they are two in number placed side by side lengthwise of the cylinder and two in'number placed end to end around the cylinder, thus occupying one-half of the surface of the cylinder; and at the other end of the type-cylinders each will carry a one-page form occupying an appropriate remaining quarter of the surface of the first cylinder, this form thus extending longitudinally over one-quarter of the length of the cylinder and circumferentially extending half-way around the cylinder. A mainweb W, equal in width to half the length of the type-cylinders, will be used for the production of the two main sheets of an eight-page paper, and be led directly between the cylinders 10 20, as shown, and the supplemental web S will be of a width equal to one-quarter of the length of the printing-cylinders and of half the width of the said main sheets. The main web W will be printed on one side in passing between the type and impression cylinders 10 20, and upon the other side in passing between the type and impression cylinders 40 30, the printingplates of which are disposed, as we have seen, atone side of the machine. This main web lies smoothly over that portion of the cylinders 20 30 which is not provided with grippers 3 4, and after being-perfected is led over the rollers 37 38 passes up and is bent over the turning-bar 39 and under the turning-bar 49, and thence is led outward toward the delivery end of the machine, being thus transferred laterally to an extent equal to its width and carried to the opposite side of the machine to that at which it entered, whereby it is made to travel over that half of the machine through which the supplemental web runs, and in advance of the turning-bar 49 it is led over guide-rollers 43 44, and running under a guide-roller 45 is entered upon the pins 18 of the deliverycylinder 41. The first sheet length entered upon the cylinder 4:1 is retained thereon, so as to make a second revolution with it, and as the second sheet length from the web W is laid upon the first sheet length upon that cylinder it is severed by the cutting devices of the cylinders 41 42, so that the product upon the cylinder 41 will then consist of two sheets of the length of the circumference of the cylinder, each sheet bearing four pages of printed matter and constituting an eightpage product. The supplemental web N will be of half the width of the main web, and being directed to between the cylinders 23 24 will have its ends impaled by the pins, say, 6, and be carried upon the surface of the cylinder 21 until the cutting devices of the cylinders 23 21 act and sever it into asheet length which is traveling at half the speed of that at which the main web is moving, and when the head of this supplemental sheet which over- 1 lies the throw-off plate, as 12, is approaching be led upon its surface and carried thereby into contact with the form near the end'of the type-cylinder 10, and thereby be printed.

upon one surface. As'the cylinder revolves, the the grippers 3 will appropriately open to deliver this supplemental sheet to the grippers 5 of the cylinder 30, which will transfer said sheet to the surface of the cylinder and carry it'outward between that 4 cylinder and the'type-cylinder and into contact with the form upon the latter, by which it will be printed upon its opposite side, and when the grippers 5 reach their co-opcrating point with respect to the cylinder 25, the grippers 16 of the latter cylinders will take said sheet from the surface of the cylinder 30 and deliver it into the tapes 35 36, by which it will be carried'under the roller 45 and be led into contact with the main web, which also passes around said roller. The arrival of the supplemental sheet at the guideroller 45 will preferably be so' timed as to make said supplemental sheet underlie and accompany the second sheet length of the main web W as it is passing the roller 45 to enter upon the cylinder 41, and hence it results that three sheets of equal length are superimposed upon the cylinder 41, so that the combined product resulting is a three-sheet paper that is delivered from said cylinder to the rollers 48 49 and directed out over the folding-rollers 90 91 to be folded between the latter by the descending folding-blade 70, thus forming a threesheet product, the outer members of which are of twice the width of the inner member, and the combined whole constituting a ten-page product.

The foregoing sufficiently illustrates a practical use of this improved supplement-introducing mechanism, but it may be remarked that products consisting of other numbers of sheets may be produced by the entire machine illustrated by a suitable disposition and duplication of the plates and suitable modification of the final delivery apparatus.

Herein the receiving-cylinder 20 is shown as separated such a distance from the carrying-cylinder 21 that their peripheries run some distance apart. This is a desirable structure, because it provides room for the grippers 3 to travel without contact with the sheet on cylinder 21, over the end of which sheet they must travel a distance while standing open and thus projected into a position ready to close and seize said sheet, and this separation of the cylinders also provides a working space for the throw-off plates which carry the end of the sheet into the range of action of said grippers and insure their positive action in seizing such sheet; but these cylinders might be placed nearer together, the sheet-seizing grippers 3 have substituted for them sheet-receiving pins, and the pins 7 be either stationary or reciprocating, the pins substituted for 'the'grippers 3 then protruding into recesses, as 71, in the throw-off plates. These throw-off plates, although of great advantage, are not essential, since it is practical to omit them, and, by giving the grippers 3 (when grippers are used) a greater sweep, partially made through-recesses in the face of cylinder 21, the leading ends of the sheets are first raised from the cylinder 21 and then clamped to the cylinder 20 solely by the action of the grippers; The cylinder 21 is shown as provided with the cutting-slots 8 9, coacting with the cutting-blade 1. While this is practical and advantageous, it is also practicable to have the cutting mechanism independent of the cylinder 21, and arrange it to so operate as to sever the web into sheets and deliver them in succession to the sheet-retaining devices of the cylinder 21.

Although the cutting devices are referred to as actually severing the web, it is practical in most cases to have them operate to nearly but not fully divide the web, aconiplete separation on the line of division being efiected by the subsequent strain upon the nearlyseparated parts. the organized machine illustrated is made to perform the office of an impression-cylinder, it may be provided with means fitting it to successively receive one or more main or large sheets, as well as the small or supplemental sheets, and with means for delivering such sheets collected upon its surface, as is common in the art of printing a web of paper, cutting the same into sheets and delivering sheets, either fiat or to other mechanisms for imparting folds thereto. The cylinders 21 22 may be made circumferentially small enough so that the small or supplemental sheet which they form and present for association with the main sheet shall not be long enough to protrude beyond the cutting-line upon which such main sheet is severed from a web, when Although the cylinder 20 in ultimate association of the sheets is had upon the surface of cylinder 41. The object of this reduced size is to prevent narrow strips or clippings being severed from the edge of the supplemental sheet.
